So I tried making my first real jet, I've made some before but they were all really small and simple. This one has been going fairly good, but for some reason after about 10 seconds or so of flight time the engines turn off and produce a black smoke. I've tried seeing if it was the landing gear hitting it or something but I can't figure it out. Help? https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=3346571844
